SD-pair Shell Model Calculation of Even-even Mo Isotopes

利用SD对壳模型讨论了偶偶Mo核低激发谱的集体性质.发现当SD对按照如下方法来确定,即对于两核子体系,通过对角化表面δ相互作用哈氏量,将SD对取为01+态和21+态,该模型可以合理的描述偶偶Mo核低激发态的集体性质.

The SD-pair shell model was applied to study the even-even94 Mo-100Mo. It is found that with the SD pair determined as 01+ and 21+ states of a two-valence-nucleon system with a Hamiltonian, which contains the single particle energy term and the Surface-Delta interaction (SDI) between like nucleons, the collectivity of low-lying states can be described reasonably.
